Description

Clicking "Edit" on a host that was provisioned as a virtual machine (with Libvirt 0.9.8 as a compute resource) results in the following "Oops":

This is with Foreman 0.5-nightly-ba71c565 on Ubuntu 12.04. Libvirt is 0.9.8.

just to be on the safe side, can you also attach your vm xml dump?

File list_volumes.rb.patch list_volumes.rb.patch added

The problem root seems to be that our Libvirt hosts use LVM-based storage pools and Fog chokes on that. There is no volume format for LVM pools but Fog doesn't correctly handle that. The attached patch sets `format_type = nil` which works around the problem. With this patch editing a host that was provisioned as a virtual machine works again, as does viewing virtual machine details of a host. So this needs to be fixed in Fog, not Foreman.
